To perform anterior thoracic auscultation, you would ask the patient to displace the breast tissue when necessary to auscultate the lungs. The diaphragm of the stethoscope is preferred because it transmits high-pitched sounds. You would instruct the patient to breathe deeply and slowly through the mouth, not the nose. Mouth breathing decreases air turbulence, which can interfere with the interpretation of breath sounds. If a patient has coarse or dense chest hair, it can be dampened to prevent the distortion of auscultatory findings. It does not need to be shaved.
